NL2 Turned trips facing turn raise.

As you say 3bet pre is preferable. Maybe check back turn. You can always get 1 more street value from weaker hands on river.

Yeah at NL2 you shoudl've 3b around $20c there. It gives you more info, since in this case villains are unknown. Those UTG min raises at this limit are usually medium to small pairs looking to get flops, so could be MP call behind (or a suited hand).

As the hand went though, check behind turn and reevaluate on the river. He's never calling your cbet on the flop with other than flush draw or maybe a set of his own.

Remember, these small stakes are all about value, unless your reads on villain is otherwise.

You definitely want to squeeze here. You wsnt to isolate vs the fushy not-full-stack.
You can xb turn and see river.

On this turn, probably not many worse hands are calling, so checking back is fine. Betting is not terrible, I believe, but we have to fold to the raise.

No, can't fold getting close to 3:1, even if he is never bluffing with a worse hand. Equilab!
